A method of minimizing cross-talk between optical modes propagating in a multi-mode optical fiber, comprises superimposing a plurality of optical wavefunctions; determining a relationship between superpositions of at least some of the optical wavefunctions and at least one measure of orthogonality of the optical modes at an output of the multi-mode optical fiber; and identifying a superposition of at least some of the optical wavefunctions that provides a desired or optimized value of the at least one measure of orthogonality using the determined relationship. The method further comprises generating, using light from a laser and at least one optical component, the identified superposition of at least some of the optical wavefunctions that provides the desired or optimized value of the at least one measure of orthogonality.

Minimization of cross-talk in a multi-mode fiber

A method of optimising at least one measure that is a quadratic function of a wavefunction, such as the spot size of a laser, the method comprising: superimposing a plurality of wavefunctions; determining a relationship between the superimposed wavefunctions and the quadratic measure, and using the determined relationship to identify the superimposed wavefunctions that provide a desired or optimised quadratic measure.
